Landscape Changes in the Kitchener Avalanche Path, Aoraki/Mount Cook National Park After the Record‐Breaking July 2022 Storm

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Three‐dimensional landscape changes were investigated in the Kitchener Avalanche Path, Aoraki/Mount Cook National Park, New Zealand, after an extreme storm in July 2022. The Path features an earthen diversion berm constructed in 2018 to mitigate the risk of avalanches to the adjacent Aoraki/Mount Cook Village.

Improved Geoid Determination Based on the Shallow-Layer Method: A Case Study Using EGM08 and CRUST2.0 in the Xinjiang and Tibetan Regions

Terrestrial, Atmospheric and Oceanic Sciences, 2013
In this paper we present the concepts and realization of the shallow-layer Shen geoid determination method, which is quite different from the classical geoid modeling methods (Stokes¡¦ method, Molodenskii¡¦s method, etc.), for determining the global or ...

Beyond Geostrophic and Gradient Wind: Enhancing the Estimation of Climatic Wind Fields From Radio Occultation

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Wind approximations, such as geostrophic and gradient wind, are limited in their ability to accurately represent atmospheric conditions in the presence of significant planetary wave activity. Those approximations, while widely applied in synoptic‐scale wind field estimation, fail to capture the full complexity of atmospheric dynamics under ...

Breaking the Temporal Resolution Barrier: Projected Performance of Hybrid Gravity Satellite Ensemble by the Early 2030s

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Limitations in the temporal resolution of contemporary gravity satellite missions hinder the precise monitoring of rapid Earth surface mass changes. By the early 2030s, unprecedented high‐temporal monitoring of Earth's dynamic mass redistribution will be available using the temporal gravity field derived from the Hybrid Gravity Satellite ...

Comparing Slab Viscous Dissipation Under Slab Distributed Weakening and Slab Segmentation Scenarios

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Subduction of cold, dense oceanic lithosphere is a key driver of plate tectonics and mantle convection. However, how much gravitational potential energy is internally dissipated by slab deformation during subduction remains debated and largely depends on the mechanisms of slab weakening.

Asymmetric Crater Relaxation on an Ice‐Rich Ceres Driven by Insolation

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Ceres has a high ice content within its crust and is the closest dwarf planet to the sun. The resultant high insolation levels at Ceres' surface (in comparison to the outer solar system) leads to high variations in surface temperature, which is dependent on both latitude and orientation of the slope (i.e., equatorward‐ or poleward‐facing).

The Climate Modeling Alliance Atmosphere Dynamical Core: Concepts, Numerics, and Scaling

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract This paper presents the dynamical core of the Climate Modeling Alliance (CliMA) atmosphere model, designed for efficient simulation of a wide range of atmospheric flows across scales. The core uses the nonhydrostatic equations of motion for a deep atmosphere, discretized with a hybrid approach that combines a spectral element method (SEM) in ...

SWOT Sheds Light on Seiche Oscillations Within Atoll Islands

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract This study investigates the occurrence of surface elevation oscillations, known as seiches, at the atoll scale. We show that the innovative Ka‐band Radar Interferometer (KaRIn) onboard the Surface Water Ocean Topography (SWOT) satellite makes it possible to visualize seiche‐like structures within lagoons of French Polynesia.
